چکیده
NHNA: nevoid hyperkeratosis of the nipple and/or areola INTRODUCTION Nevoid hyperkeratosis of the nipple and/or areola (NHNA) is an uncommon skin disease without welldefined etiology, reported for the first time in 1923. The disease is characterized by slowly growing verrucous thickening and brown pigmentation of the areola or nipple. Here we report a lesion on the nipple clinically and dermoscopically identical to a small-size pigmented basal cell carcinoma. Nevertheless, histopathologic examination suggested the diagnosis of NHNA in a very early stage.
